JOURNAL PACKING.

No Drawing. Application filed yriay 10,

To all whom it may concern Be it known that I, CHARLES A. GELIN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in a Journal Packing, of which the following is a description.

My intention belongs to that general class of products known as a journal or like packing, and relatesparticularly to a packingparticularly suited for lubricating purposes. together with the preferred method of manufacturing; the packing. The invention has among its objects the production of an efiicient, reliable, inexpensive and satisfactory packing which will be extremely durable and satisfactory for use under practically all conditions. Many other objects of the construction herein shown and described will be obvious to those skilled in. the art from the disclosures herein given.

To this end my invention consists in the novel product and method herein shown and described, and more particularly pointed out in the claims.

Heretofore, it has been customary to use cotton or wool waste, or a mixture of the two, in journal boxes to carry the oil and apply the same to the journal. However. the cotton and wool waste have a tendency to mat down and become hard, and in time to fail to function properly. The life of the same is comparatively short, although the same may in some cases beremoved from the box and cleaned and replaced. However. it quickly mats down again, owing to the weight of the contained oil and lack of resiliency, and consequently may let the jour-, nal and bearings run dry. In some instances the cotton and wool waste has been supplemented or replaced by cocoanut fiber, but this product is generally gritty. and it has a tendencyto heat, it packs and mats down, consequently its utility and efficiency is not what is should be. v

l have found that a very desirable, efficient and inexpensive journal packing can be made by utilizing wood fibers in the form of excelsior, a coarse grade of excelsior being preferred. I also prefer 'excelsior made from wood which is substantially free from ,QI'lt or mineral matter embedded in the cell walls. It is well known that certain woods have a tendency to carry up mineral crystals, grit, etc., which become embedded in ough] y Specification of Letters Patent. Patented July 18, 1922,

the wood cells, the amount varying in different woods. It also is found that the evcelsior from somekinds of woods ismore resilient and does not break as easlly as QXCQlSlOl made from other woods. I have found that by taking an excelsior made from poplar. basswood and similar woods, a very desirable and free from dirt, dust and grit as pos-q sifiblee and as before mentioned. in the shape oflong; and not too line threads or shavings. if the same is notthoroughly dry, prefer to dry the same outso as to drive substantially all of the moisture out of the cells and then before the same has had an opportunity to reabsorb moisture from the atmosphere, Iprefer to treat the same to the desired extent with an oil or the equivalent which would have more or less of a waterproofing effect and would form substantially a film over the wood, keepingthe moisture out. The result is that the excelsior having been dried out, it is apparently much more resilient or springy that when wet, and the oil does not. to any appreciable extent, seem to affect the resiliency. While,'of course, oil is applied to the e'xcelsior when in the-jour nal boxes, this preliminary treatment is generally desirable in order that there may be no moisture accumulated after the drying and before the packing is placed in the journal box.

In some forms of packing, I prefer to combine with the excelsior a mixture of cotton or wool waste, or cotton and wool mixture, the excelsior and waste being thorintermixed so that the various strands or strings of both are intertwined.

Extensive and severe tests have shown that the packing thus produced is far superior to waste alone or to waste and cocoanut fiber or similar packing. It has been. found that the wood retains its resiliency for long periods and at all times maintains the waste and packing in contact with the journal, thereby thoroughly lubricating the ame. The capillary attraction seems also to be-increased, and the wood has a polish ing effect on the journal. While I have mentioned the use of a mixture oi. treated exeelsior and waste, this is a matter of preference, as in some cases the treated excelsior alone may be preferred to the mixture.

Having thus described my invention, it is obvious that varlous immaterial modifica-' prising resilient Wood excelsior treated so to be free from moisture.

3. A journal packing oi": the kind described consisting of: a mixture of wood excelsior, treated so as to be substantially free from grit and suitable waste, the same mixed in suitable proportions.

4-. A journal packing of the kind described consisting oi a mixture of Wood excelsior, treated so as to be substantially free from moisture andsuitable Waste, the same mixed in suitable proportions.

5. A journal packing of the kind described comprising a mixture of treated dried WOO(l exeelsior and wool or cotton Waste. 4

6. A journal packing of the kind described comprising a mixture of coarse resilient treated dried Wood excelsior and Wool or cotton Waste.

7. A method of making journal 'packing consisting in forming Wood excelsior from a wood having resilient properties and substantially tree from grit, drying the same to remove the moisture, then treating the same with a coating of suitable material repellent to moisture. 1

8. A method of making journal packing; consisting in forming Wood excelsior from a WOOCl having resilient properties and substantially tree from grit, drying the same to remove the excess moisture, then treating the same with a coating of suitable material repellent to moisture and thence mixing the same with cotton or WOOl waste in the de sired proportion.
